    Me and my friends all got Meiosis. But who knows...
    Maybe I read the question wrong... if it asked how the embryo divides, it's defo mitosis. If it was meiosis, each new cell would have 23 chromosomes which would make like ..... a sperm baby... or something O.O''''''

    For someone who really isn't good at Science, I feel it went alright. For the Plantains one I got for a disadvantage - the process isn't as quick as the large hearing machine. That sound okay?

    Is this the catalyst question or plantains?

    It was because some people stopped counting where the line stopped curving upwards - where it went completely flat at the top. Others, like me, stopped counting when the line turned downwards. Not sure which is right. Didn't know what the flat bit at the top was supposed to represent LMAO.

    I thought it was 2 minutes because the first 30 seconds the blood flow was constant because muscles didn't need the extra oxygen because they were fine aerobically respiring, and then the next 1.5 minutes of the graph rising as blood flow increased due to prolonged exercise.

    For Anaerobic respiration, is it fine that I said it's the incomplete breakdown of glucose to release energy. Forgot to mention that it doesn't use oxygen :/

    I did the opposite to you. I only mentioned it doesn't use oxygen. Will I get the mark still?

    How many minutes was the athlete exercising for...? And was it meiosis or mitosis?
    I put 1.5 minutes as it levelled off so I assume that the athlete was just paying back oxygen debt and I'm pretty sure it was mitosis as it said a fertilised egg cell.

    I think oxygen being mentioned was the key there, so yes, probably you would get the mark

    I put 1 min running and it was Meiosis.
    It was mitosis because it asks what happens when the egg is fertilised to become a embryo, it produces lots of identical cells

    i thought the first thing i was organs so i wrote testes why is everyone saying meiosis

    Posted from TSR Mobile
    They are talking about a different question. Where the cells were produced was the testes. How they were produced was meiosis.

    Yes I put 1 minute too. I think it's 1 minute because he doesn't actually run home again.

    I got so confused over the plantains questions, probably from all the math yesterday Did anyone get a disadvantage for the catalase one? I wrote that the enzyme could be expensive to produce
    It said hydrogen peroxide doesn't kill every bacteria

    For the 4 marker about how the heart rate or something like that helps the athlete during the run, I talked about how more blood is able to reach the muscles, more oxygen is able to reach along with glucose which will give energy to them. Also lactic acid being removed so the muscles can contract? Idk
